• pete: Running into the same issue. Was there any resolution on this?

Answer 1

Check error message from your logs:

net.masterthought.cucumber.ValidationException: No report file was added! 

This message is shown, when something is wrong in the configuration of Maven Cucumber HTML Report plugin.

Also check Cucumber version in your POM file. Update your project with the latest available Cucumber version or anything above 4.0.0 version.
